I hope they don't treat this as just recurring revenue opportunity. The thing that bothers me the most about this is that they are switching to a SaaS model, but only offering 2 different options. I think they are blowing a major opportunity for both increasing revenue and to expand the opportunities for the users. I have a feeling if they continue down the path they are heading, they will actually end up losing money instead of increasing revenue.
I believe that if they offered monthly access to additional features such as rendering, larger number of drawing sheets, drawing blocks, etc. (for a fee of course) Ability to download the other libraries and use them? Maybe offer different tiers of the software for different rates that offer more than what the current offerings?
I think they could actually make this a good thing if they approach it from the customer perspective. I know everyone is getting super tired of having to pay monthly subscription fees for things we used to be able to own outright, but if they actually increase the value to the users instead of just trying to increase revenue, I think this could be a win-win.
