Reminder, as many times before...
Anyone can pay cheap $ to pack yet more nodes on already saturated providers. This does nothing for diversity against NSA, GCHQ, BND, RCMP, AFP, FVEY+, etc... who all share fibre taps, and Sybils, all who trivially exploit tor. The simple plausibilty of such is all documented in whitepapers, and in curious cases of parallel construction.
Your odds at frustrating these adversaries are much better if you: 1) Place nodes where there are no nodes today by AS and jurisdictional geography. Don't ask who's popular, permissive, and cheap, that does nothing, ask who has naught but one other node, and finally do research on your own to find who has none. 2) Develop a PKI person to person in real life verified node infrastructure between yourselves that users can subscribe to. 3) Analyze the fuck out of node metadata and feed that into subscribable path options. 4) Don't prop up yet another Linux box.
Seems NO ONE is doing this yet, since years worth of being informed of it. That's a shame.
