This is a lousy article rehashing an article behind a paywall.
The cost they have is $87 a month. There is so much that's confusing about this. They don't specify how many streaming services they are counting in that, but it's a good guess that is about 5, each at about $17 a month. I feel I have too many streaming services and share accounts with family, and I can stream from about 7, pay for one and watch 1.5. If I couldn't share accounts, I wouldn't have the accounts. I pretty much watch star trek and whatever show someone tells me to watch.
They also don't specify what $87 a month gets you in cable. Around me that's about basic cable prices, which is significantly less content presented in a less convenient format and is almost entirely reruns filled to brim with commercials.
Not only is the article missing key information it also misrepresents the information it has.
Note: I'm sure people will tell me to pirate everything, but there are reasons to not pirate. And it doesn't address that this is a poorly written article giving incomplete and incorrect information.
As far as longevity of models go, I built a necron army when they came out in 3rd ed. Two sets of models would be suspect now, wraiths and the tomb Spyder. One set of models no longer exists in the game, pariahs.
That was about 20 years ago. You'll be fine.
Paint what you buy and don't buy if you had models to paint. Also know that your models look great.
