I'm also inexplicably giving money to LinkedIn. I signed up for their premium plan so long ago, back when it was 200 something a year. They recently shot the price straight through the roof nearly doubling it while removing some features and restricting them to even higher paying tiers.
I however, have been grandfathered in to the original price and keep all the original feature set. However, if I quit or cancel my subscription or there is a lapse in payment I lose this benefit forever.
It's scummy as fuck. Designed purposely so I never let go.
