Unfortunately, the reality is that prices just go up - internet access, cell phone, streaming TV, electricity…very little in my experience costs substantially less over time.
I do use both BackBlaze and Are (to Wasabi) to have two cloud backups. Probably overkill, and probably time for me to rethink the strategy, but I have had to restore from cloud backup twice over the past 10 years (not everthing, but in both cases a significant amount of data and files that I would have been unhappy to have lost).
Another perk of cloud storage, which I have posted about previously (no idea where that thread is). A few years ago, my daughter traveled some 1500 miles away for graduate school. The day after she arrived, her MBA died (turned out, eventually, to be a dead system board, but that’s another story). With one day before classes started and her desperately in need of all of her data and a working computer, I was able to order a new MBA at the local BestBuy, have her pick it up, remote into her new computer, install Arq, and restore her files from her Arq backup. The next day, when classes started, she was ready to go and that was worth the cost of the online storage.
Everyone’s needs vary, and one way to look at BackBlaze is to ask the question of how much recent data can you afford to lose? If, for example, losing a month of work would not make any difference to you, you might do just as well with an offsite drive that you bring in once / month to clone your system to.
If, like me, however, the most important files tend to be the most recently created, then a more continuous backup strategy makes sense, and BackBlaze (and Arq) do provide a hassle-free way to accomplish that, albeit at a higher cost. (I guess one might argue that if you replaced your backup hard drive yearly, the cost of the drive is going to be pretty close to the new cost for BackBlaze each year, so you aren’t really saving money…)
