Advertising is one of the main reasons modern social media is experiencing continued enshittification in this era. Noam Chomsky in his "Manufacturing Consent" wrote of three "filters" that determined which content would be presented to viewers, and while he wrote on the mass media in 1988, I believe this framework applies equally to social media in 2024: access to capital; the "advertising license to do business;" and a symbiotic relationship with government, who provides access to authoritative sources of news.
Take X, for example: its access to capital allows it to eclipse most other social media and build network effects that are difficult for other startups to disrupt; after the Musk acquisition, advertisers began withdrawing from the platform; and as the Twitter files have claimed, its collusion with the U.S. government in the promotion/demotion of certain viewpoints.
If you want to see genuine viewpoints, you'd best seek out media that are largely independent of these three "filters" over what messages are permissible on the medium.
