That's the thing, it shouldn't be a business practice at all. Browsers are part of the Internet infrastructure and that should not be treated like any other business but be regulated enough to ensure anyone gets fair use of the infrastucture and should rely primarily on public funding.

The Internet being global makes this challenging, and almost all countries (including so-called democracies) wanting to drink as much authoritarian juice as they can get away with does mean that there is plenty of risk here as well. But letting one or a few giant megacorporations entirely dicate the primary intrastructure for information interchange is so much worse.
