We don’t require you to pay.
We stop developing and supporting a Plugin that was available fro Free, for years.
That is all.
If you require a Plugin suite that does things like Toolset – yes, we do not offer that for free.
I think this is the reason the Plugin is as well still available here, and the WordPress Forces did not remove it, as it does not force you or scam you in any way.
We even offer full support and bug fixing up and end 2018.
We announced this way in advance, to give users a valid chance to look out for alternatives (for software that does register Custom Types, Taxonomies and fields, not something very extreme if you ask me)
Thanks for your point of view thou, I suggest, if you want Types to be removed, this is the wrong forum to ask for it.
I then rather suggest WordPress Plugin review, or similar.
