The prices have been increased in (a not so recent) past - as can be figured out by the age and content of this topic thread, which essentially notifies and warns Plesk users.
In essence, it could have been known to you.
In addition, Plesk (formerly Parallels) offered a perpetual license allowing you to renew at (relatively) low renewal rate - and that renewal scheme still exists now.
In short, when having bought the perpetual license in the past, the current price increase would not have been that painful.
Nevertheless, I do agree to some extent that prices have gone up in a way that is not entirely proper : it harms the Plesk community as a whole and it will sooner or later harm Plesk as a company, since the extra revenue of increased prices will not balance with a (future) decrease in revenue due to "lost customers".
But it is not our job to evaluate Plesk as a company or it's policies (!).
It should be our focus to (still) see the merits of Plesk as a hosting panel : in essence, you can go with cheaper alternatives - this choice will not benefit you in the long run.
In my humble opinion, the discussion should not be about prices : we all have the freedom of choice to stop using Plesk (!).
And if we decide to continue with Plesk : we should be fair and not discuss the pricing, since it is actually "part of the deal" and the result of our (own) choice.
Again, I personally want to emphasize the value of Plesk as a hosting panel - as opposed to the discussion about Plesk licensing costs.
A small tip : just do not buy the licenses from the Plesk store - there are cheaper (discounted) alternatives around.
