It's tricky. Could Salesforce donate to organizations that are patching where Texas is failing (such that Bumble and Match's CEO are doing [1]) instead of offering relos out of Texas? Absolutely. Does that make it any better for those who are subjugated by extremist Texas legislative policy? It lessens the pain but the pain is still there, but to your point, the policies won't change until a critical mass of voters vote in less extremist politicians. This
will happen at some point [2] [3] [4] as conservative voters age out and younger voters and immigrants (regardless of origin) become eligible to vote, but there is arguably a lot of value in accelerating the progress towards reducing the suffering of the disenfranchised. Money is speech, right?
