MS really dropped the ball after IE6. Notably in Europe Firefox actually temporarily surpassed IE in market share, before Google came and stomped everyone.
I recall a blog from that time titled Chrome is the new IE6.
On the corporate side, we paid attention when an SAAS site had a "Built For Internet Explorer" badge. Elements can+did falter in other browsers (because devs only dev'd for IE).
So--one part we're an ad company and one part MS-style "embrace and extend" the web.
Basically, these adverts are blasted at you 5-8 times a day depending on how many YouTube videos/shorts you watch, also I recall seeing same advert even on someone's FB timeline being shared by their friends to switch to chrome.
A decision reached because both
informed & consent
are minimized as much as possible. This is a core method of unethical marketing.Pity about Mozilla having recently switched to the dark side themselves, becoming an advertising company as well.
