I am interested if people here think this is okay or not.

In short, they sold lifetime license for their own product (KingSumo) that functioned as Wordpress plugin and recently remade it into a SaaS. We were informed on email to give new version of KingSumo a try. I couldn't login and was then informed I have to pay for it because it is separate from the wordpress version that I paid for.

I posted about it in their facebook group, which caused uproar from all buyers, but eventually they shut it down and any new post I make gets deleted immediately.

What do you think of this? Is it too much to expect the $49 or $149 licenses to apply to $8/mo new version?

Someone else wrote this: (which feels to me like it makes sense) "Now, we have invested in a plugin, they took our money and converted it into a SaaS model. That does not feel ok. The plans for this must have been known 3 months ago, when you sold the plugin version. It simply makes the lifetime deal from last November feels like a type of crowdfunding to get funds for the new version…"
