I don't expect that to last. There are many influential countries that are increasingly intolerant of LGBTQ+ at a government level. If one of them just so much as mumbles something about "moral values", expect all of these over-eager LGBTQ-supporting companies to quietly delete all references that they ever supported this.
Maybe next it'll be european/american actors that get put on the chopping block?
While you may be on to something that it's not purely altruistic there's a much more important reason for that stance.
You lose out on a lot of very well educated, highly competent candidates for your workforce if you don't at least try to provide an inclusive work environment for minority groups.
Smart employers figures that out a long time ago.
