None of them are 'evil', lol. You wouldn't have most of the technology you use without them.
Not really? A lot of the modern internet was built on this vaguely hippyish idea of free use and communal knowledge building; these companies are just attempting to financialise it by any means possible (in meta and alphabet's case, by turning their "users" into products themselves). They're not really the primary innovators, and their domination has largely made the world wide web a worse place.
Sure, these companies didn't invent and don't own the internet - but they created and manufactured a lot of the technology we use to access the internet. Almost all operating softwares used by computers that are used today were developed by Microsoft and Apple largely pioneered innovation in terms of smartphones, which is why you have so many companies like Samsung today trying to compete with the iPhone.
You are partly right that their monopolizing of certain markets has been detrimental to the World Wide Web, but that does not make these companies evil - what that means is government policy should be more conducive to private-sector competition.
