To be fair, this is describing oligopolic capitalism in general; streaming services is just where it's most visibly on display for the general public. But the same modus operandi is pervasive throughout the economy: attract customers with good deals initially while maximizing lock-in by all means at your disposal, then start fleecing them. There's simply no economic incentive not to do this, and ethics don't even enter into the equation at the scale those companies operate.

In a more diverse market, competition provides some, albeit limited, check on all this, but very aggressive anti-monopoly regulation is required to keep the market diverse enough for that. I don't just mean breaking up actual monopolies, but even any semblance of market dominance must be mercilessly crushed to maintain competitiveness. Any form of "laissez faire" in the presence of private property inevitably leads to oligopolies.
