Governments don't want people to protest over anything bad they do. They want them to sit nice and quiet and let them take the decisions themselves, so they've criminalized almost any type of protest. The few types of protests you can do today are because other people have fought for them before us, too. But ideally, the Governments wouldn't want you to protest at all, whether you do it in crowds or on your own on Twitter.
From a current Government's view, all revolutions are illegal, too.

This is the very definition of a government's job in many western countries. The government is elected by the electorate in order to make decisions on our behalf while we get about our lives.
Whether or not governments "allow" protest to certain levels or not is a different matter, but the design of most current western democracies is one that should, in essence, not require significant levels of protest, since they were elected to do exactly what they're doing by a plurality (or even majority) of the electorate.

Ideally, would anyone want to protest or want other people protesting? Ideally, I certainly wouldn't. Of course, in our less than ideal world, sometimes it is necessary, but unless they're doing it for fun or attention, I doubt anyone "wants" to have to protest.
