It's not as if people switched just because it had Google branding. Everyone switched because it was quantifiably better. From benchmarks to design, Chrome was a winner, and has enjoyed its success.
Now, Chrome is doing things that could be seen as "IE-like." Manifest v3 -- even with relaxed changes towards ad blocking -- will not necessarily enable uBlock Origin to continue exactly as it does today. The forced user system is another move in the direction of anti-consumer behavior.
I've tried to switch back to the competition. I'm using Firefox right now. Pages render faster and compact mode is great. But Handoff myseteriously doesn't work on my Mac when it does with Chrome (added in Firefox 65). I had to enable U2F support with an about:config flag. I had to turn off the spell checker to fight mysterious input latency in average textboxes.
I'm reluctantly staying because I ultimately like what I see, but there's an undeniable truth somewhere in here. It's really hard for Firefox to match Chrome simply based on resources. Google can drop millions of dollars on a browser -- and few other companies can afford to do that. Certainly not Mozilla.
