This is nonsense
"The browser is a connective tissue between our professional and personal lives and the larger world, as more and more facets of it become digital-first," the Firefox maker wrote.
Nonsense. The browser is a tissue between my professional and personal life - what is he talking about? And what is digital-first? So what is second?
You might think this is just Mozilla being bitter and crying over the fact that Firefox has fallen out of fashion. No one's forcing you to install or run Chrome on your non-ChromeOS desktop, for instance, so we surely must do it under our own free will.
It was nothing about free will. Google strong armed its installation through bundling with other programs, particularly antivirus. It also completely disrespected the way programs should be installed, by circumventing the Program Files directory on windows which in corporate worlds usually is protected via admin passwords. It was all about getting the user "used" to Chrome and thus any new device, it would be installed almost immediately. Google wanted Chrome to be synonymous with the web like the Internet Explorer 'e' icon used to be, and has basically achieved this now.
It also pushed its own browser when you used Google services. Rather than making their products truly cross-platform, they were just lazy/evil and didn't bother to make them work as well in competitor's browsers. Then also developers got lazy and only wanted to bother making things work in one browser (and so many of them are married to Google). Even today, there are some sites where I just can't get them to work properly without going to Chrome.
