Does anyone know when Microsoft joined the RIAA and what MS had to say about that? I'm curious what reason MS gave for it, if any.
The RIAA was founded in 1952 so it couldn't have been a founding member, yet I can't find any news or press release with permutations of "Microsoft joins RIAA". Based on archive.org's oldest copy of the RIAA website's members page, it was a member since 2016 at least.
Not sure, but they've been on good terms since the Zune era at minimum.
