Because it’s an uphill battle against monopolies.

Blah blah blah the same argument.

If you had a better product than Windows, for free, everyone would use it. You don't, and you blame everyone except yourselves.

Yellow card for ageism, ha-ha.

Oh man am I having my first 'these fucking kids' moments? I think I am.

Oh, so a piece of hardware the vendor of which didn’t care about Linux support. How is this an OS problem?

Because if I can't use my tools with one OS, but I can with another, then the problem is with the OS that I cannot. Scanners are common peripherals my dude. Do you think windows would have sold if it didn't support scanners?

be pissed at Linux and its community if it’s a device driver problem.

I'm pissed at the linux community because their answers were antagonistic, elitist, and useless. You asked for one example, I gave you one example yet the community has responded in the same way each time.

In your example the problem is with the vendor of the device.

Keep thinking that way and waiting for all vendors to start distributing their own linux drivers, see how far you get.
