This seems to be a common thing in some OSHW stuff I've seen.
Some people will take your work and sell it for massive markup but the support is expected to be provided by the creator (and a lot of the issues stem from the fact that these sellers might substitute parts for cheaper ones that don't meet some critical specs like timing or TTL compatibility for example)
When those creators say they aren't happy with that arrangement all they get is abuse - sure everything is legal but it doesn't make the behaviour any less immoral or scummy.
