Biden signed a few anti-trust acts into law and also issued executive order 14036 to try to reign in anti-competitive practices. Trump quite literally revoked every one of these within his first month returning to office, calling them "bad for business".

Who is it actually bad for? The consumers. The new religious-linked GOP no longer believes in fairness or holding business accountable for anything, it's "God's will" or something...

Media consolidation is actively encouraged by the current regime in the US because it lets them have more control.

You have the Trump administration and the Congressional Republicans to thank.
