The terms of linux don’t come into play unless I try to re-use some other licensed code to make a profit, and that would still fall under copyright law rather than any kind of terms&services clause. Installing a piece of software doesn’t constitute an agreement unless there are clear terms given at the beginning of the installation (and even then it has been pretty questionable in court cases). There was nothing presented to me to agree to during the installation and I’ve never once been asked to agree to anything during the installation of any software on my computer. There’s no need for something like this in most linux software other than the standard disclaimer that it comes with no warranty. Still not anything I had to click to agree to, it just happens to be on the websites for the distributions.
Even if you want to try and pretend that I somehow agreed so some nonsense conditions by installing linux, it still doesn’t meet your conditions of putting myself at a disadvantage to the manufacturer. Surely you’re not trying to suggest that my “disadvantage” is that I can’t take a group to court for my own failure to use software which was freely given and distributed, and of which very little was even written by the distribution maintainers? That would be as absurd as claiming that I had to agree to an EULA before installing my operating system. Hell I don’t even agree to collecting data about package management on my system.
