Yes, each airbag vest costs money to produce, that’s why you pay for them, and why it’s shit that this company is charging an ongoing subscription that actively disables them when you miss a payment, because the vests they’ve already sent out don’t cost them any money to maintain
And yes, each copy of a backported security update doesn’t cost meaningful amounts of money, but you’re not paying for just a copy of one update, you’re paying for an ongoing service that provides constant backports of security updates for loads of packages (and if you’re a personal user, as other people mentioned, you don’t even have to pay for that!), those backports are not free to maintain, companies charging for extended support that is nothing new, especially when they’re long term support distros targeting enterprise
Typical, so many of the people who complain about the existence of SBMM in games are people who want to be able to constantly stomp players who are worse than them (when people complain about “not wanting to sweat all the time”, this is pretty much guaranteed to be the actual reason)
While I don’t doubt that Halo and CoD have flawed matchmaking, people usually use those to say that SBMM as a whole is a bad thing, or even that it’s “ruining gaming”, when it exists for good reasons and benefits a lot of games
You rarely see people complain about it in fighting games for example, usually when people do it’s because the developers of a given game have designed an original system that does a bad job at actually matching skill, when a typical Elo-style system would’ve worked far better
