I see, but I don't see how an active license will serve Marketplace authors. It serves IPS more than Marketplace authors.
I am aware of this, but you guys should consider the free sources your clients are using from Marketplace. You should allow them to install any update if the app or plugin already installed on their communities free or paid.
Today I have completed 16 years as client with IPS, and you guys treat me like someone just registered his account a new member. My profile says so.
