A $5 VPS comes with several gigabytes of storage. A standard web font (e.g. Roboto) is ~1MB. Bandwidth is essentially free through CloudFlare. Who doesn't have the space or money to self-host their fonts?
Currently on HN frontpage there is an article "How to avoid layout shifts caused by web fonts" [1]. It lists several techniques you can use to reduce font size. One of the examples shows how subsetting reduces Roboto Regular size to 11KB.
