Do you feel the same about AWS?

Personally - yes.

They may not come after all the niche companies, but they definitely come after the most successful markets, especially those with low effort moats.

Same goes for relying on the Apple/Google app stores (ex - Apple literally got slapped in court for copying successful apps and then pushing their offering to the top of their stores... talk about wildly abusive behavior).

I may still choose to use AWS/GCP/Azure while trying to find product-market fit as an immature startup, but I'd look real, REAL hard at ditching them as soon as possible afterwards.

Unless you have particularly bursty workloads, they aren't even a good cost saving measure anymore.

Which side are you implying AWS is on?
