No need to apologize. I can differentiate disagreement from attack.

However, consider that this action raises the bar to run FOSS apps from:

1. Disable the toggle.
2. Install the app.

To:

1. Purchase a phone that can run an OS that allows you to do the above.
2. Disable bootloader unlock.
3. Connect your phone over USB.
4. Flash the OS.
5. Do the above.

OR:

1. Do the above.
2. Connect your phone to USB or enable wireless ADB.
3. Run a command to install the app (repeat for every app install)

The new barrier to entry is going to inevitably catch a whole lot of people who would otherwise be willing to go out of their way to install FOSS apps. Development will also suffer as a downstream consequence of this.

I use postmarketOS too, and it is a much more pleasant experience to use than having to break out a second device to update or install software. It has a large number of issues, but it’s more comfortable to use than your comment implies.
