I acknowledge it may not happen but cloudflare hasn't done anything to make me doubt them.
Isn't backblaze still just a single datacenter?
There is nothing weird postulating about using a storage service with the lowest price among cloud providers with (planned) free egress on a show HN thread.
You are certainly free to disagree if free egress actually matters but cloudflare R2 is the first to offer free egress AFAIK. B2 may be cheap at 1ยข / GB but that still adds up once you start moving TBs around.
Lots of variables and unknowns and room for debate.
But yeah, comment sounds so weird for a non released product.
