Now I just use Safari because all I do really is read stuff.
Obviously Google has many income streams. Mozilla does not.
It always comes down to the question: do you want to pay money for a browser? And the answer for 99% of the users is "hell no".
I looked into it, but couldn't get over the pretentiousness. They seem to make plenty of money from either investors or customers because they're not bankrupt yet, so I guess there must be a demographic that likes being treated like that.
There's something funny about a browser pretending it's the best thing since sliced bread telling me to drag the downloaded application to the macOS dock after downloading the Windows setup file.
Pretentious or not, Arc is pre-enshittification. Chrome, Edge and FF are not, which is what matters.
It was fast. At some point it had its own install of Adobe Flash so you could get rid of your regular Flash install and run two browsers: one without Flash as your main, and use Chrome for those few websites that require Flash effectively isolating them from your regular web experience, until this eventually became moot, it was another WebKit browser, albeit with V8 instead of JavaScriptCore, and pioneered per tab process isolation so rather than your whole browser crashing, just that one tab would. Prior to Chrome, whole browser crashes were not uncommon, oftentimes because of Flash (giving another reason to want to isolate it, although plug-ins I think were also isolated).
What Chrome subsequently became is the very definition of enshittification, and you can pinpoint it to around the time Google started trying to force people to link their Chrome profiles to their Google Accounts.
I removed it right away. I just want a browser, not whatever that was.
