There's no indication for people stop playing it. Considering you don't have to pay sub to check out new content at base game level lot of people come back for updates.

Businesses who are lucky enough to come up with a truly iconic product aren't likely to deliberately discard that product.
You're not going to see Apple shelve the iPhone and then attempt to corner the market in, say, VR headsets instead.
You're not going to see Dyson shelve their vacuum-cleaners and then divert their attention to wacky desk fans and hairdryers instead.
You're not going to see Porsche shelve the 911 and start tying to make the best delivery vans possible.
Unless a company is absolutely convinced that their existing product is on it's last legs, and that a completely new product is guaranteed to be an even bigger success, they're not likely to abandon an existing revenue stream.
My original point was simply that
IF FDev decides to cease development of ED then there's little point in worrying about it.
Conversely, if that's
not the case (which seems more likely), then it's daft to think they're going to provide perpetual free updates, thus negating the benefit of the LEP.
