Because computers and smartphones, the law has since been extended to also include the case where you own no TV but either a PCI or USB tuner, or any internet access that includes TV streaming (e.g those that come with a set-top box, or those extra options on mobile plans).
This was a despicable period and since then the law has changed. Now there is no license fee on owning a TV receiver. Instead everyone pays a tax whether they own a TV, a computer, whatever and no matter if they watch TV or not.
"Once upon a time, the government tried to impose a tax you had to pay if you had a TV or a computer, which was bad because even people who never watched TV would have had to pay it. But it's better now, because instead there's a tax that literally everyone pays, even if they don't watch TV and even if they don't have a computer."
I'm struggling to see what principles would make the first situation bad without also making the second one bad.
Ideally the individual cost is very low, so it’s not outlandish to have everyone pay, especially as even if you don’t watch it, you benefit from the diffusion of qualitative culture and news in society.
By not making everyone pay, this public service has to compete for attention with commercial ones and risks drifting away in quality.
The counterpoint is that such a state-owned channel could become a propaganda tool.
But both are bad, the former more so than the current, at least.
Personally I agree with a mandatory monthly cost but it is way too high, should be in proportion to household income and the people in the upper ranks of the broadcasting companies shouldn't earn absurdly high wages and pensions.
Despite that I like to support proper journalism that is accessible to everyone and content that is often ad-free to watch/listen/read.

The issue for me is mostly that I refuse to pay for the bucketloads of despicably low quality content they put out. A shame, because there’s Arte (TV) and FIP (radio) which have quality stuff, but they only get a fraction of it.
