First, you are not the first to suffer unreasonable taxation. Some years ago, shortly after this blockchain had arisen, a massive increase in new users swelled our ranks with ~1m people that began posting, commenting, and voting. Almost all those new users (I was one of them) have now left, driven from the platform by unrestrained taxation that you and your community are presently experiencing.
There is a sound financial reason, which you allude to in your OP above, for doing this. The original ninaminers (Steem tokens were originally created by mining) had complete control of governance of the platform because they had the vast majority of stake, and voting for witnesses is stake weighted. By controlling the most tokens, they controlled the witnesses, and the witnesses controlled the code. The distribution of tokens to the new users threatened to reduce the majority stake of the ninjaminers, and that threatened their control of governance, which threatened their income from the rewards pool.
Read this, and you will understand the way that downvotes (taxation) maintain control of the blockchain by the oligarchy on Hive.

I hope you fare better than the vast majority of new users on Hive, who choose to leave when taxed 100% of their earnings here by oligarchs such as Acidyo.
Thanks!
Edit: I have tipped you because from your description of Acidyo's intentions and actions towards you, I expect him to DV (tax) away 100% of the upvotes on your post. He cannot tax tips. Please consider that mechanism going forward, and add it to the discussions your community undertake regarding your future on Hive. Tips are not taxable events, and can, as I have here, be used to encourage and reward Hive posts and comments without being subject to downvotes.
