I mean it isn’t but sort of is at the same time. It firstly depends on what kind of kickstarter it is. There are many ways where its just a system for a publisher to gauge interest in the project. Those are typically just preorders however many others are just throwing money into a well and hoping something comes of it. I get people’s hatred of crowdfunding and it can easily be a trap. Where a ton of people are just there to get the money and leg it or who are simply too incompetent to use the funds properly. Hell even experienced developer can be too incompetent, double fine studios/Tim Schafer is a poster child for this. While I love their work, they had a horrid run with crowdfunding and I guess it should have been expected since they are always late and overspend on their budget when they were working with publishers.
Now with all the negatives said, I think crowdfunding in all its forms can lead to wonderful project that simply couldn’t have existed due to a lack of interest by publishers. Hell I doubt we would had Baldur’s Gate 3 without crowdfunding and this isn’t talking exclusively about BG 3 since the Divinity Original sin games really got the ball rolling for Larian Studios. Crowdfunding can lead to the rebirth of genres once thought dead.
Like I agree with your general point but this has nothing to do with online games licensing besides its being pulled from digital store fronts. Brick and mortar stores can have product recalls as well and this would likely be in that same category of problem (its a bit weird with preowned games since publishers were already given their cut) so they can continue to sell those but a brand “new” copy may have suffered a similar fate but we have to remember Spec Ops the Line is from the 360 era so I doubt there would even been many “new” copies around. Also I can’t fault publishers from just “deleting” a game from existence because spending thousands for merely upkeeping the licenses for a game they realistically haven’t sold in major volumes for nearly half a decade (at minimum) seems a tad bit unreasonable. Most music labels likely aren’t even going to sell a perpetual license as well, so its a can of worms of people wanting to get their cut.
