"Looking for Creative Suite 6? The latest versions of all your favorite apps like Photoshop and Illustrator are only available with a Creative Cloud membership."
So LR might be still available as standalone. Or might be not.
Though I think it rather continues to be - there are quite a few alternative options available and though not all are at the level of LR they get better and better.
Plus the trend is to go as a one stop editor rendering at some point Photoshop and similar pixel editors much much less important - meaning there might be even less incentive to pay rental for one app only. Which reminds me I paid 75€ for LR nearly 2 years ago, which is like 4€ per month compared to 12€ as rental. I don't use much Photoshop-type of applications and I have that base covered by an alternative which is absolutely fine for my type of edits. For a hobbyist, I try to avoid services - in the end, small payments consume not so insignificant amount in total. However for pro-s I can see the point.
