While there are concerns about Google trying to monopolize the internet (or possibly create a duopoly with Amazon), Big Tech's controversies are digging it's own grave. On the other hand, Mozilla's been also digging it's own grave in recent years because of it's own controversies. What I see happening is Google's going to make Microsoft, Apple, Brave, and Mozilla gradually become irrelevant (which is already happening in one way or another), but because Google has a graveyard in it's closet, they're going to continue to lose users in terms of YouTube, Android, search engine usage, Google Services, Chromium, Chrome, etc, and that's going to eventually kill them (which is also already happening). As that trend continues, other search engines, operating systems, video sharing sites, browsers, and services are going to develop more of a presence (and that's slowly becoming a reality as I type this). Even if Amazon does jump on the bandwagon, they have a mountain of controversies as well, so it won't take long for them to become replaced by something else.
