Yay, internet arguments, what better way to spend my time at 3:00 in the morning. Okay, here we go. . . .
You don't pay a subscription fee to use Steam or download and play Steam games, but your PS Plus "free" games are tied to your subscription and your ability to play them expires when that does. What you wrote sounds like rebuttal or justification, but these are different situations. Might as well be saying you're renting tap water.
Technically true, but most PS4 owners would argue that being a Plus member is more-or-less an essential component of console ownership instead of an elite snobby add-on, because Sony linked having + to the functionality of online multiplayer. I would venture to say that a plurality if not an outright majority of console owners would not really want a box that does not allow them to utilize the online multiplayer features of many modern games. For this reason, I suspect that a large proportion of PS4 owners are Plus subscribers who are unlikely to allow their subs to lapse for any significant period of time (unless they just can't afford it).
The water example doesn't work. I can fill my tub with water, and the water utility isn't going to magically take that away if I fail to pay my bills.
How secure is your house? I can non-magically remove that water in your tub with a few plastic containers and a siphon hose.
Well, yes, but you can get your money back for them. If they ban you from Steam and you've spent a thousand dollars there, they can't just keep your money and revoke access to your games.
Actually...
Valve may cancel your Account or any particular Subscription(s) at any time in the event that (a) Valve ceases providing such Subscriptions to similarly situated Subscribers generally, or (b) you breach any terms of this Agreement (including any Subscription Terms or Rules of Use). In the event that your Account or a particular Subscription is terminated or cancelled by Valve for a violation of this Agreement or improper or illegal activity, no refund, including of any Subscription fees or of any unused funds in your Steam Wallet, will be granted.
Well, this. . . plus, if you're like most CAGs, you acquired a lot of that backlog by means of sale purchases or by using card money, so there's a question of relative return on your investment. If Valve were to just hand you a wad of cash that it considered fair market value for your library and revoke your access to your library, you won't be able to go out with said wad and purchase the equivalent games.
Well, you drink water from the tap then later deposit it back into the sanitation system, and the cycle repeats. So, in that sense you are just renting water on a regular basis.
If you had your own independent septic system, like in a rural area, then you'd own your tap water.
Er, look, buddy, I don't know what sort of backwater you live in, but municipalities cannot legally recycle your wastewater as drinking water in most places. At best, recycled wastewater can be utilized for nonpotable purposes, such as flushing toilets or watering non-food crop plants. If you're drinking the same water that's carrying your waste away, I'd strongly consider suing your utility. You'd have a stronger case than guy-who-sues-Valve-for-Steam-game-access, and that's Flint-level malfeasance.
