Nowadays nearly everything is becoming more and more hostile to power users. What caused the recent Reddit protest is definitely not the first.
People who know a bit more than others tend to open up and utilize alternative venues that enable easier access to the data they want, while at the same time make the companies harder to make profit from them. As such, once third-party apps/clients that offer similar if not better features grow popular enough, it will eventually become a problem to the companies and they'll do whatever means to shut them down.
Not to mention there are app vendors who aggressively detect users who root/jailbreak or run custom systems. Security is one thing, but it's more that these users are hard to deal with both in terms of providing technical support as well as making profit from their personal data.
EDIT: It applies to desktop PC as well. Apart from VM hypervisors, the presence of some commonly used developer tools, IDEs and other utilities, that are normally not present on an average user's device, could also irritate certain games' anticheat systems causing unexpected bans and restrictions.
It's hard to change the hostility towards power users, mainly because:
- They are few compared to normal users, yet they "cause much more trouble than others".
- Little impact in long-term revenue, as there were hardly any value from their data to begin with, compared to those from normal users.
- Their voices, however loud and clear, will never have enough reach, as most normal users do not have the wisdom to understand the necessary details to be convinced, which eventually leads to their actions backfire, just like how this Reddit protest (and probably many others before this one) ended up.
There's little one could do as the companies are Gods to their own Edens (platforms). They have absolute power over everything. For that reason Fediverse existed, so that instance owners can decide for themselves while still being able to interact with others.
