Option 3: System gets implemented and you get to keep purchased commanders/skins/bulletins forever, or you can use currency earned in game to purchase/upkeep degrading commanders/skins/bulletins. Combined with a whole bunch of cool new stuff.
Relic doesn't alienate people that have already purchased stuff by taking it away, and gives a free avenue for players who don't want to pay for stuff to still get it by playing the game.
Each of these 3 are equally plausible from what little actual information we have.
If you are going to speculate, atleast consider all possible avenues, not just the ones that give you a reason to talk shit about Relic.
the problem with your option 3 is that it is a subset of either option 1 or 2 unless you do not earn ingame currency through playing (which, by the way would mean you pay for buying and for maintaining, so i doubt you meant that).
to be more clear let's break it down:
there's four ways of combining "buying" and "maintaining":
1. The way it used to be: you don't have to buy the content, you don't have to buy to maintain it, you get it for free uncondintionally.
2. You pay to buy the content and don't have to maintain it, you can use it unconditionally AFTER you payed (this is the current system).
3. You do not have to buy the content, but have to pay money to load up charges (most mobile F2P games operate like that)
4. You both pay for the content and have to maintain it (there's multiple ways this could be true)
Currently the coh2 dlc system is option 2, and it's seemingly moving towards 4 and i'd assume (like you) that paid content stays free for use (if not, there might even be legal repercussions) and only "drops" or items purchased with ingame currency will lose durability. since, to my knowdledge at least, nobody ever paid money for a bulletin, i assume that the entirety of those will cost (ingame-)money to maintain.
Now again, and i've said this before as have others: There are only two binary option how this system will work out... either you gain enough ingame currency by playing to keep the durability of your items/bulletins up, or you don't. if you do, the system is pretty useless. if you don't, the system is bad. There is no argueing this. Either you DO get enough supply, or you don't. Either it's raining outside at the moment, or it's not. There is no option 3. Whether you say "it's snowing" belongs into the "it's raining" or "it's not raining" category might be debatable, but the fact that there are only those two categories is not.
Admittedly, depending on how exactly this new "supply system" works, the answer to which of these 2 options is true might be different for different users for different reasons, but the fact still stands: there are only those two options, and imho both are not good.
