Additionally to what has already been mentioned: People are susceptible to politics that confirm their prejudices. Right-wing political thought is largely based on confirming that whatever prejudices people hold, they are morally good and justified. Thus elevating an in-group above out-groups. That is a powerful lure.
Because this confuzzled me, note that the EU’s Digital Markets Act (DMA) and the Digital Services Act (DSA) are two separate things.
The Digital Markets Act is the one which is meant to remove economic barriers by “gatekeepers”. For example the DMA is used to force Google and Apple to open their app stores.
The Digital Services Act is the one that regulates (among other things) moderation, political neutrality and removal of extremist content on social media platforms. That’s the one Thierry Breton oversaw and threatened Elon with.
So while exTwitter’s lawyers may sigh in relief, because they got out of the DMA; the DSA is still looming large.
