lol. What other browser vendors? Whatwg is just google is a trench coat. Edge is chrome. Firefox is funded by Google. So I guess apple who's main contribution is being years behind and having half their stuff be broken

> And the other browser vendors with conflicitng interests just go along with it?

When there's a conflict of interest they don't (Apple refuses to implement some APIs that would help making their walled garden app store more obsolete). But just maintaining a duopoly (Mozilla is funded by Google) is not a conflicting interest itself.

> Did you come to that opinion after engaging in the discussions with them?

With employees? There's no point. If you have a well paid job you will never accept the fact that what you're doing might not be so good after all..
