Without a doubt in my mind: absolutely.
This and previous actions on the part of Maxon seem to come straight out of Adobe's play book (which is probably why ex-Adobe management was hired to assist Maxon in this process):
First, introduce the rental model but keep the perpetual license, and make certain both are initially presented as equal alternatives. This is to ensure to avoid a user uprising. Sooth any nay-sayer users, but never allow anyone in your organization to confirm that your end goal is rental only.
Present it as "freedom of choice", or along similar lines.
Next, with each new release clearly present the rental version as the ever more affordable and attractive alternative. Incrementally reduce exposure of the perpetual license on the website in favour of the rental option(s) and reduce access to it. Keep touting the advantages for the user of rental rather than perpetual. The goal here is to slowly and seamlessly prime and groom the larger user base to accept rental as the preferred option rather than perpetual licenses. Provide extra perks for users who rent your software. Reduce perks and updates for perpetual users.
And at no time mention the end goal. Keep users in the dark. "Listen" to your users by providing additional rental options. Cater towards companies and small/medium sized businesses (which generally really like rental options due to fiscal benefits).
It is important to continuously stress the attractiveness of rental licenses, while adding more and more to the unattractive qualities of the perpetual license. Convince as many existing perpetual users to make the switch to rental. And very important here is the use of language: instead of "rent" rather use "subscribe", or even better: allow for no distinction: "buy" or "purchase". (The younger generation of users is no longer quite so aware of the distinction between renting software and purchasing software anyway. This is great for software companies.)
In the final stages before ending access to new perpetual licenses it is necessary to complicate the process of updating existing perpetual licensed versions as much as is possible. At the same time, it is expected that a segment of older loyal perpetual users will never accept rental licenses. This won't matter, since the less expensive rental model probably already increased revenue by a large margin.
It is at this time that the company will release statements about how for the sake of continued development, the benefit of improved features of the software, and the company itself that perpetual licenses be discontinued. "if it's good for you, it's good for the company, and vice versa". Along those lines.
The company may opt to keep the peace, allow this user group access to a perpetual license for the time being, but no new perpetual licenses will be available. Drastically increase update pricing, and after a few releases stop perpetual updates entirely. Or be more cold-hearted, and disallow perpetual users to update their licenses. After all, by this time that group of users is probably reduced to a small minority.
Happy company! And accepting users (for the most part).
