relying solely on cash injections.

That’s just the case. Not everyone buys lifetime subscriptions. This is a short term cash injection for investment. I don’t know their books, but I doubt the majority of their long term income will come from these lifetime subs.

There are some ski lifts that give lifetime passes. Its used as a cash injection to fund investments rather than lending off an institution that will want their money back.

Sure you’ll want your lifetime video data for free, but I bet there are a bunch of lifetime members that don’t watch much over a lifetime and/or the risk of future video watching outweighs the loan interest they’d have to pay otherwise.
