Fair criticism. I don't have a confident estimate for the number of new remote employees, but here's a hand-wavy one: one third of the 130M US jobs can be done remotely [0]. 20% of CFOs expect about 20% of their workforce to be remote in the future [1]. Assuming a uniform distribution across company sizes and no other remote jobs outside of those 20%, we'd expect 1/3 * 130M * 1/5 * 1/5 = 1.75M new remote jobs.

The assumptions here are obviously strong and wrong but it does seem like "low millions" is probably the right order of magnitude.

Moreover we can expect highly-regarded companies like Facebook and Twitter to be bellwethers for the rest of industry. If their remote work experiments succeed, I suspect expansion will follow rapidly (I expect the reverse if they fail).
