The royalties/costs from implementing HBM in products must be off the charts compared to gddr.
We havn't seen many products use it since vega VII and the frontier edition.
It seems like most of this goes into multi-thousand dollar datacenter/compute products anymore.

I wish they come with a low-cost HBM implementation.

Samsung once announced an HBM-LC once, but it seems it didn't get much attention and forgot about it.

The main idea is to use a narrower bus, narrower than 1024bit, with lower density to the point it can be used on regular organic packaging rather than requiring an expensive silicon interposer. But it seems that the total cost will be questionable compared to GDDR6 which can use even cheaper implementation (just in PCB), so the space-saving that HBM brings isn't worth it after all.
