They should stay private and build on the quality brand they have rather than trying to grow because reasons.
So you think with fewer variants, one of those few is more likely to meet your needs? Doesn't having more variants make it more likely that one will suit you, or at least get closer?

Yes, because being over-specced doesn't matter if it's cheap enough.
In 3D printing in (say) 2019, for instance: It was ridiculously common to use a Raspberry Pi with a printer -- for all kinds of reasons. They were cheap (enough), and they worked well (enough), and they were available (enough).
Few, if any, questioned whether the Raspberry Pi was the right thing to use, for it was ubiquitous and well-understood.
But when Pis became more expensive and/or less available in 2021 or so, people didn't just stop doing stuff with their printers.
They instead found alternative platforms to do things with: They bought used corpo mini-PCs, repurposed cheap-shit Android TV boxes, used old Android phones, and (of course) trudged through the weeds getting things working various other SBCs.
Literally throwing the baby out with the bath water.
