Why streaming services are dumping shows left and right

There are two reasons stated in the article, and I have some commentary on each.

First is that if a service removes a show from its offerings, then it doesn't have to pay residuals to the various unions/guilds that own the show rights, and income goes up. While that makes mathematical sense (subscription revenue is constant, assuming people don't react quickly to the change in streaming inventory), I wonder whether it's also an attempt by studio-controlled streaming services to exert more influence over the currently on-strike WGA. If WGA members' residuals drop substantially, they might stop supporting the strike.

Second is that there's an accounting trick where you get a tax write-down when something you own is damaged, and taking your own asset off your own service is an "impairment" that counts as such damage. Perhaps companies like Disney are self-inflicting these multi-billion-dollar impairments right now to offset and even mask the additional profits that they're seeing from their recent price hikes.
