There is no moral imperative to use or not to use BeeMe. Use it if you want, don't use it if you don't want to, but intellectual property is a dead imaginary construct. It is completely irrelevant in a decentralised context. If somehow @steemchiller were able to successfully serve a takedown request to the hosting provider, someone else would host a new version almost immediately.
@steemchiller once had my deepest respect. I voted all of his support posts when he started making them and used to beg him to open-source his tools and receive rewards through Utopian.io when it was still alive, or at least run for witness. I was always frustrated that instead of doing that, he would keep complaining about how bad his life was financially. Now I don't want anyone to struggle in silence, but it's very frustrating to watch that happen to someone while they completely ignore your various suggestions to better their situation.
All that was just frustration, but then watching his decline into Justin shill status has just been terrible. I had hope for him briefly when he published a post which was critical of Steemit Inc's decision to soft-fork and freeze accounts. Unfortunately I cannot link you to that post, because it was censored by Steemit Inc on their API servers (which only they still run) and is no longer accessable through any frontend.
They censored him, and I thought he'd get really pissed then and maybe realise he should come over to Hive! But no, what he did erased every ounce of respect I ever had for him, or ever might have again.
He put his fucking tail between his legs, kowtowed to Justin, and ran for fucking witness. So fuck it.
Use BeeMe.
