Some other hosting companies provide something smaller, e.g. Digital Ocean only allows 16 IPv6 addresses per VM (presumably out of a /64 shared with many other VMs).
That would be profiteering, allocate only a few and charge extra for more addresses.
I think it is more "IPv4-thinking" rather than profiteering. They only allow 16 IPv6 addresses per VM - that's all they think anyone could need! There is no mechanism to obtain more. IPv6 address management should be about abundance, flexibility and ease of configuration, rather than IPv4's scarcity and manual micro-management.
An ISP that had a single /64 shared with all it's customers could easily allocate a /96 to every customer and never run out - no ISP is likely to get 2^32 customers.
A cloud provider could get a IPv6 /32 for ~$1k/year (or $0 depending upon RIR and IPv4 address holdings) and give a /64 to 2^32 customers at a cost of ~$0.00000023/year each or a /56 to 2^24 customers at a cost of ~$0.00006/year each. More customers than that? - get another /32 ... there's 2^29 of them available, and the more you get the cheaper they are!
