I think there is understandably a 'nervous' reaction that Discovery being a prequel has retarded the franchise. That it might not make two seasons let alone three, four or seven. Going back in time was both safe and weak. I fully expect the time frame to go forward after the Discovery experiment runs its course.Who is "they"? The last twelve years- yeah, paramount went with a reboot. They didn't continue the TNG era even though they wanted to a few years earlier, and Berman, understandably didn't want to do more TNG era. This reboot film series did well until the 3rd movie.
Discovery is different. It is not "avoiding" the 24th century. It produced Fuller's vision for a first season, even if he was fired. And we don't know what's to come, but the 24th century was originally part of that plan.
Saying they've avoided the TNG era for 12 years, (as if there is some kind of aversion to it) is the same as saying they haven't produced a series in 12 years. The studio doesn't care what era it's in as long as it sells. The first one to break from the Berman era was Berman, the TNG king, if for no other reason than being sick of it, even the studio wanted more of it.
Also, Nemesis did very well in DVD sales, having the number 1 spot in the US and UK the week it was released on DVD. Did the studio break even? We don't know. Probably not.
Did the studio break even on Beyond? We don't know. Probably not.
TNG First Contact was very successful. Insurrection much less so, but enough to merit an additional, and unplanned sequel, Nemesis, which flopped(Even if it ended up doing extremely well in DVD sales and rentals).
ST09 was very successful, STID less so, but certainly good enough to merit an additional sequel, Beyond, which flopped(even if it ended up doing very well in DVD/BR sales).
Should there be an aversion to the reboot Kirk era as well?
It's just your opinion/perception, and just my opinion/perception disagreeing,and seeing it differently. There's nothing to refute.
It's like when people say "Killed the franchise." the franchise has never stopped, not even for a year since maybe the 70's, and even then there were projects and plans in the works for Trek the whole time.
I don't understand how there is a thought TNG killed the franchise, it re-invigorated it. DS9 didn't kill it. It was followed by Voyager. Each of those proved themselves with seven season of popularity. Enterprise followed and still had four seasons. Too early to declare Discovery is anything other than five episodes one season in. It could be Trek's death knell for all we know or it might limp on. Who knows?
