CF: No criminal convictions I know about. No reason to distrust yet. Most controversies seem to be about providing services to political organisations.

GCP: Earth Engine is quite good, but Google have multiple criminal convictions. As a repeat offender they should be avoided at all costs. They are just so exceptionally good at manipulating people, markets and academia it's genuinely terrifying.

AWS: Pretty useful, annoying to use, distrust because I can't bear Amazon's use of dark patterns in consumer products.

Same way I do about any large corporation, I don't trust them.
