Bullschit. They used those specials to fix their cash position and they're now kicking off the top tier to maximize their balance sheet. Subscribers were taken advantage of. They knew full well what they were doing then and do so now.
They've reached a critical mass where they no longer need volume but to rather maximize profits off a smaller base. Makes managing their network easier, lowers input costs, increases operating margins and they can in all likelihood show the same profit. Their brand they believe is resilient enough to deal with the fallout.
It's business. Schit business for the consumers, and bordering on unethical imo, but just business. Greed at the expense of the consumers...
