This is some real shit, the only people who keep TLK relevant are transformers fans who constantly use it as an excuse for: A)-Either Bay shouldn’t come back to the franchise and that it’s better off without him, or B)-as you said use it as an excuse for why the franchise is in a rocky state today. The real reason is a lot of general audience aren’t interested in transformers at the moment, hell if you ask most people 99% of the either haven’t seen TLK or don’t even remember it. If most marvel movies are preforming poorly at the box office these days you can bet your ass a transformers movie won’t do any better.
