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.

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!
