I know a few who recently moved from LearnDash to MemberPress and suggested I use it, but I discarded it when I noticed it belonged to Awesome Motive.

Currently, I am testing Sensei, and I find it a good LMS. Easy Digital Downloads and AffiliateWP are plugins I cancelled the renewals when they announced they sold to Awesome Motive and have already replaced.

At this time, I rely primarily on plugins directly tied to either WordPress or WooCommerce instead (meaning Automattic), and plugins I know the devs behind it, that are maintained by small independent ventures and have a bright future ahead.

This kind of thing happening with one of their plugins is unethical, not illegal, but lacks consciousness.

Each time a plugin does something that I consider unethical, enforced, or even increases its price significantly, my action is to find a suitable replacement, migrate the data, and remove the plugin while having the new thoroughly replacing it without further ado.
