the sign that they've grown out of love with HitB is how they're putting zero to no effort to keep up with movies either good or bad. They basically have grown out of love with Plinkett too.
And honestly if they are more willing to put the effort on BotW and Re:View that's fine by me, seeing how that's their best regular content. No need to force yourself to do HitB constantly if you can't even bother to go watch ok movies like they used to.
IIRC, they said that in terms of production costs, a Plinkett Review costs way more than anything they do (short of their actual films like Feeding Frenzy or Space Cop), while it doesn't earn them much more than an episode of Half in the Bag or Re:View. And a Plinkett Review has the highest liability for them, being the biggest target for copyright strikes and Youtube takedowns. Higher costs + moderate returns + higher risks = bad investment.
Although money isn't RLM's prime motivator, as Mike loved trolling the audience with bait-and-switch fake reviews, even though those were known to
cost RLM money (they damaged RLM's overall Youtube profit algorithms, hurting RLM's revenue across-the-board, and weren't "clickbait" easy profit generators), but that was a price Mike was willing to pay for a good joke, until humorless fans complaining too much about being the butt of the joke made Mike stop doing it.
I think the current hurdle on Plinkett Reviews is that they're all on Mike. Unlike the rest of RLM's content, which shares or rotates the responsibility, Plinkett Reviews are exclusively Mike's responsibility. And he doesn't always have it in him to tackle a job that big, not unless he's excited about it.
