No, what it is doing (to borrow the analogy from an eralier posting) is opening every letter in an evelope, putting the contents in a see-through bag and adding a new addres label.

You should also be using DKIM, SPF and DMARC if you are bank, a financial institution, or other domain which is high risk for forged phishing emails purporting to be from you. This allows the recipients to differentiate between your legitimate emails and forgeries.

Which would just be a notification to the would be thieves that you have a phone worth stealing!

Yes, if you want to run java, run it as a standalone app not in the browser.

Allowing the browser to access to locally installed fonts (for rendering text) should not be a problem. What should be disabled is the ability for the browser to inform the web server about the installed fonts, as well as other characteristics of the system.

The problem with retractions should be easier to deal with in the online domain than in print. Make it a rule that whenever an article which is subject to a retraction is requested that the retraction is automatically, and prominently, included in the page served.

They should pay the costs for their connection to/at the Internet Exchange Points (IXP) the same way the ISPs pay for their connections to the IXP.

Nor carry anything which is mains driven rather than battery operated - so no corded only electric shavers in your hand luggage (Do long haul flights have a shaver socket in the bathrooms?)

Why would the takedown notice be sent to the ISP? Would it not be sent to one of the contacts in the WHOIS for the domain?

Do most DMCA notices not just require taking down a single URL rather than all pages in a domain? In which case it is the site owner, or their webmaster, who has to action the notice, so sending the notice to the ISP will just delay the process.

I disagree with your disagreement of the analogy. What if your house is rented or you have put the physical letter is in a safety deposit box in the bank? In both these cases the physical location is owned by someone else and you are just renting the space. Is this any different from you renting the e-mailbox space on the google (or other ISP) servers?

Someone should tell Goldman Sachs that you cannot unsend an email. Usenet articles can be cancelled, even though most servers ignore cancels, but like snail mail, once email is posted it cannot be recalled.

But having opened the safe, can they force you to 'decode' the entries on a paper document which are written in a code or cipher? If not, then they should not be able to force you to decrypt an electronic document which is written in 'code'.

Even before AOL there was CompuServe with its octal user IDs

In which case the manufacturer should have upgraded OpenSSL and released (maybe even pushed) the update.

When the Heartbleed exploit was announced, all users of vulnerable openssl versions should have upgraded.
