mozilla kept complaining about google, yet they accept their juicy money by selling their users in 2 decades, they could have built their own search, many tried and many found success! mozilla kept complaining about the playstore, yet they happily put their app there in 2 decades, they could have built their own store, many did! Sometimes i wonder what Mozilla's real intent is, where did the money go?
