The only reason why so many companies are openly in support of LGBTQ+ is that right now it costs them almost nothing and effortlessly paints the illusion of a human face onto their public image.

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.
