Been a long time since I set foot in a data center; are tape drives not still king for cold storage of data?
Comment on Say Hello to the World's Largest Hard Drive, a Massive 36TB Seagate

And I would go so far as to say that nobody who is buying 36 TB spinners is doing offsite backups of that data. For any org doing offsites of that much data you are almost guaranteed using a tape drive of some form because… they pay for themselves pretty fast and are much better for actual cold storage backups.
Seagate et al keep pushing for these truly massive spinners and I really do wonder who the market is for them. They are overly expensive for cold storage and basically any setup with that volume of data is going to be better off slowly rotating out smaller drives. Partially because of recovery times and partially because nobody but a sponsored youtuber is throwing out their 24 TB drives because 36 TB hit the market.
I assume these are a byproduct of some actually useful tech that is sold to help offset the costs while maybe REALLY REALLY REALLY want 72 TBs in their four bay Synology.

It depends on the size/“disruptiveness” of the company but yeah. You either have your own tape back up system or you contract out to someone who does and try not to think about what it means to be doing a glorified rsync of all your data offsite every week.
I wouldn’t quite go so far as to say anyone doing genuine offsite backups using a spinning disc is wrong but…

I can’t criticize other hobbyists. I only back up locally and I use Synology Hybrid Raid to do it.

Was this a typo? I would expect that almost everyone who is buying these is doing offsite backups. Who has this amount of data density and is ok with losing it?
Yes, they are quite possibly using tape for these backups (either directly or through some cloud service) but you still want offsite backups. Otherwise a bad fire and you lose it all.

I wouldn’t buy a Synology but either way I’d want a 5 or 6 bay for raid-6 with two parity drives. Going from 4 bay (raid 6 or 10) to 5 bay (raid 6) is 50% more user data for 25% more drives. I wouldn’t do raid 5 with drives of this size.
