I have long advocated a middle-ground here:
**Whenever you compromise your values, APOLOGIZE for it**
Instead of insisting on absolute purity, we can accept that real-world trade-offs happen. But don't present it as normal business, ASK to be excused and explain the situation.
In this case, SFC etc. should have some qualifier every place they reference the Google or Microsoft sponsorships. Something like an *acknowledgement* that this is a compromise and link to a statement.
