I'm not a legal expert/lawyer but I do think a lot of this is not the company just randomly wanting to do it, but lawyer driven development. No company wants to introduce more friction for no reason, unless somehow there's precedent or risk involved in not doing it. Curious to know what legal precedents or laws have changed recently.

The only possible non legally driven reason I can think of would be if they think the tradeoff of extra friction (and lost customers) is more than offset by fraud protection efforts. This seems unlikely cause I don't see how that math could have changed in the last few years.
