You are right but im certain that the amount of incidents like that is really small. A little more common is the situation where someone renting runs out of money and squats to avoid going homeless.
Both types of squatters above are overrepresented and the most common one by far is the anti-capitalist squatter.
People who are fed up with high rents. Not without motives.
Corps buy entire building blocks, sometimes for renting but a lot of times just for storing capital and playing with the market.
This combined with airbnb raising the prices more for tourists while salaries i. spain stay the same ends up in rents being totally disproportionate.
Most squatters I know don't want trouble, they get inside abandoned buildings and stay unnoticed for a big lenght of time. Getting inside a building in active use is just asking for trouble, as annoying it may be for the owners it's not the best option for the okupas either.
