Rent-seeking patterns are typical for competition-limited markets (or markets where there isn't sufficient competition).
For example, various Linux distributions have now agreed to develop a shared app store based on Flatpak.
No, I will never install standard free/open source software as Flatpaks or Snaps, but I can and will consider it for very old versions, and – especially – for commercial applications.
So, even though RedHat (Fedora) and Ubuntu are pushing towards closed gardens, their products being frameworks inside of which users operate in, with the intent of convincing proprietary partners to support them as "industry standards" and thus together garner a majority market share, the basic pressures of a healthy competitive market has even here found a technically better solution that allows fair competition among co-operating competitive entities.
True danger isn't that companies and organizations choose bad practices; it is anyone getting a high majority of the market, even if they avoid the worst monopoly practices, because it lets them skew the rules of the game in their own favour. We need fair competition, at all scales. That, and only that, can really thwart rent-seeking behaviour and other such, due to sheer competitive pressure.
