There's a lot of "such that..." and hopeful language there. I don't see it playing out so easily as that in the real future. And it doesn't seem to me like any of this actually reduces Cloudflare's carbon footprint. Incentivizing other people to do things has no real bearing on whether or not they will do them (see Trump's dedication to bringing back coal for example) and also has nothing to do with Cloudflare's carbon footprint.
They are grandstanding with this post. I see their technology as wildly beneficial to the planet, but the attitude that they can pollute and just "offset it" is ridiculous and I think, a major problem with how we are looking at addressing these problems.
