FFmpeg vs. MPEG-LA royalties

Sure, you can claim that people aren't obliged to pay up to the cartel, but that's like claiming people don't have to pay their road tax or their television licence.

This is a good comparison in fact. Nobody would think about banning cars and television worldwide just because in some parts of the world you have to pay a tax to use them.

Right, but I'm not advocating a "ban". I'm saying that by introducing a de-facto standard based on known-encumbered technologies, Google and friends are setting people up for such taxation. And I think that there are those of us that grudgingly accept things like genuine taxes and regulations because there is some kind of pretense of accountability and common sense behind their imposition. So, although some Free Software project may let you, for example, operate some kind of radio station, one has to grudgingly accept that for various reasons, there may be other restrictions from place to place that curtails the practical exercise of the freedoms/rights/privileges described in the software licence.

Where patents are concerned, however, there are those of us who do not consider them to be legitimate, not least because the system that upholds patents is not accountable - it's practically set up to enrich itself as its primary objective. Now, when such instruments collide with Free Software licensing, I would certainly wish to disregard them entirely and insist that they impose no limitations on the freedoms/rights/privileges described in the software licence. However, in practice, patents are used to undermine the usage and distribution of Free Software.

By licensing the MPEG patents for themselves (contrary to advice which apparently casts this strategy in a dubious light), Google acknowledges an obligation which resides beyond the software licence; through their market position, they proliferate this obligation, and then "to compete with Windows" or "to provide a proper experience" everyone becomes exposed to this obligation; since this obligation may impose unreasonable burdens on some parties (it may not be affordable for them to license the patents, for example, or maybe the cartel tells someone that they live in a "bad" country), it thereby excludes people from exchanging Free Software, thus dividing the community between the rich (with the privilege of using and distributing Free Software) and everyone else.

Google's actions are more like a strong dose of car advocacy, or even an act to mandate car ownership, when having a car at the very least probably doesn't make sense for many people, and it might even be an unwanted financial burden for others. All I and others are trying to do is to encourage more sustainable alternatives.
