Mozilla is a 501(c)3 non-profit. It doesn't have a massive revenue source like Google, Microsoft, and Apple in the funding of their browsers. In fact, Mozilla has historically relied on Google for funds. Today, there's a lot less cash being thrown around. There's massive economic uncertainty due to the whims of some governmental executives, a long-slow war in Eastern Europe, and an expanding war in the Middle East. Interest rates are up. Very "up".
One of the few things people with too much money are willing to throw money at is "AI". 5 years ago it was "blockchain" and 5 years before that it was "VR", but today, it's AI. Mozilla NEEDS to look like they're going all in on AI to attract more funds because stupid people with money are told that AI will make everything more efficient, faster, and accessible.
In that time, while funds are being reduced, a non-profit needs to reduce its expenses. It's very likely that Pocket and Fakespot provide too little benefit to too little of a userbase for the expense to maintain the programs. About the two programs--
I used Fakespot to help shop on Amazon. I liked it and I'm sorry to see it go. I also know no one in the real world that knew about it. Amazon actively hated and submitted multiple complaints against Fakespot resulting it it being delisted from the Apple App store at least once. That said, there's a lot of computing power required to analyze and index ALL Amazon products. It seems like a very expensive product to maintain. It makes sense that it's getting cut.
Pocket is just a bookmark/article storage app. The principle is great "bookmark something to read later on any device", but that also means maintaining account infrastructure cloud storage, updating settings, etc. I think the most interesting thing about Pocket is to investigate just how many saved articles were visited later by their users. I'm willing to bet that fewer than 10% of articles saved for later reading were even clicked on ever again. That's not intended to be a dig at Pocket, Mozilla, or the users of Pocket, but more of a commentary of how we hoard things "just in case".
Lastly, let's talk about the sale of user data. Mozilla previously said, "Never" and now is saying, "Only safely". Before you call them traitors to life, consider asking "Why?". Might it be because they're desperately low on funds from prior contributors and need to find SOME sort of revenue to keep operations going? And if they have to sell user data to keep the doors open, isn't it best that they do so in such a way as to not be able to to personally identify any of their users?
It just seems that this article's author is quick to condemn Mozilla for being less righteous today than yesterday while it's trying to stay afloat in a sea of competitors who make no effort or illusion to righteousness. The article is akin to screaming at your child for getting a B+ after having missed 2 weeks of class while in the hospital.
