In the case of Chrome, you can't blame Google. They made a good browser, did some marketing and it got popular. However the current situation is worrisome, because alternative implementations are dying and in the case of the web, diversity is important. Both Opera and Microsoft's Edge are now powered by Chromium. Chromium is a project controlled by Google. Its redeeming quality, in terms of its open source nature, is…
Microsoft has the resources to fork Chromium if necessary, much like Google forked WebKit (after sending patches upstream for a while) and Apple forked KHTML. This is just how open source works and isn't a problem in itself. By doing this, Microsoft gets compatibility with the world's websites on day one, and they can take it from there. It's a smart move that many people seem to be misinterpreting.
If google’s killing ad block extensions, Microsoft will most definitely follow suite.
Your only best bet is Firefox right now.
Chrome is a Trojan horse and Google most definitely doesn’t give a shit about your privacy.
