My observation and personal opinion.

IPv6 and NOSTR share a similar issue.

There is no financial incentive to push adoption of a protocol.

There is incentive to push the adoption of a solution, even a FOSS solution, as there is a commercial insensitive to do so.

Even with FOSS, there is potential sponsorship or the commercial opportunities arising from adoption of your product / service. nostr:note12fax0wzftn05759v366wn2dkwxxyxj4nxc0r3fluqs3adjgr4essc6rjv5
