Look, I will absolutely criticize Mozilla for some of its policies. Pretty much every issue you've raised there is spot-on, in fact I'll go a step further and remind everyone that Pocket was kind of supposed to be Open Source by now, and it still isn't.
But it's cutting off your nose to spite your face to use Chrome. Google is less receptive to criticism than Mozilla is, has worse extension APIs and is more restrictive of how extensions get installed, has worse privacy features, allows for no extensions on phones, is more directly tied into an advertising network, and is actively trying to make the web worse.
Use Firefox.
I am not telling you to be complacent or to ignore Mozilla's problems, I am telling you not to lend support to the browser that is actively trying to make the web worse. We're all very happy for you that you're very principled about not just picking the better of two bad options. We're happy that you have those standards. But we're less thrilled about your policy of picking the worst of two bad options. At the very heckin least you're not even going to use a Chromium fork? You're just going to make the worst browser choice you can make for the Open web?
