This feels like a narrow sample size so I wanted to add a another data point in response.
Most vegetarians or vegans I know in the UK choose to be so due to the same reasoning you aspire to... reduction of their carbon footprint.
And because of the increased levels of cruelty associated with industrial farming practices.
The percentage who don't like the taste or the idea of killing an animal is relatively minor.
Their figures work out at an average of $221,809 per job
And even more in New York where it's $252,169.
Given average wages in the IT sector are nothing close to that it goes to show just how much is being pumped away at the top.
Another vote for Gandi but to answer your question specifically....
Trustworthy?
Gandi are widely regarded as being the most ethical registrar out there so if behaviour to date is a good indicator of future trust then their reputation speaks volumes.
Hidden costs
No hidden costs. They do tend to be a pound/dollar or so more expensive, however that leads me onto...
Privacy
Comparison
There's horrible companies out there who engage in question practices so it really does make a difference who you go with
To give an example here's some of my experiences with 1&1 which might help you understand the sort of difference a good registrar makes....
To go into that last one in a little more depth it means that they insist on auto renewing your domain and will charge you to transfer a domain away so it's often easier just to pay.
Eventually my CC details with them expired and I decided to just let the domain go rather than continuing giving them money.
However in response they started sending me ever more threatening emails about my CC card being expired and then sending letters to my house saying they'd pass the debt for auto renewing my domain on to a collection agency!
What's worse tho is the domain name didn't need renewing for 8 or 9 months but they had reregistered it anyway just to try and make me pay even tho they knew my CC details were expired!!
Ps. No affiliation to Gandi, just a fan that thinks they've proved themselves as a company and deserve your money. Also think Namecheap are pretty good, though Gandi would be the one i'd recommend first and foremost, particularly amongst slashdotters!
The idea that Linux itself is somehow massively power inefficient are, I expect, wildly ignorant.
The fact is that in order to get the sort of battery life that a Macbook running OS X does requires that the kernel/drivers/software all be optimized for that specific hardware.
Likewise, mobile phones running Android get exceptional battery life because their power output is tuned to the hardware.
And as for servers, engineers already design for maximum power per watt - the notion that there are datacenters wasting megawatts of electricity just because they're running Linux is asinine.
Was blown away by what they've doing here (note: I was the original submitter), however the thing I found bizarre - particularly in 2015, and given their target market is techies - was the inclusion of a DVD drive bay...
Battery life is arguably one of the most important features of any laptop, particularly amongst Linux users where - due to a lack of OEM tuning - installing Linux on other laptops typically only brings around ~2/3rd of the native OS's battery life.
Leaving space for an extra HDD or SSD is sorta cute but even individual SSD capacities are huge nowadays. If they absolutely had to go with the extra bay, it's a crying shame there's no option for second battery.
To their credit they're promising a 13'' version sans DVD drive next, however this perhaps only goes to reinforce that the additional of a DVD drive in the 15" model was an overstretch
Who knows, perhaps even someone from Purism is reading this and could enlighten us as to the choices they made?
I guess except those that do not drink alcohol whatsoever (God I feel sorry for them, when they wake up in the morning, THAT is the best they're gonna feel all day!!)
nicely put, tho 'waking up like shit and feeling that all day' is what keeps me a non-drinker the other 6 days of the week!
No one cares and it is just a boring day job with no passion left. This new CEO needs to excite her employees and fire QA and security people and provide a vision for improvments.
I remember a similar company, popular for a while a few years back, that given their name, you would of thought were born to execute on such a strategy.
