As a matter of principle, those in bandwidth-constrained situations should be browsing via proxies or browsers that automatically compress, such as Opera Mobile back in the day, or Google’s more modern compression baked in to Android/Chrome. (If it still exists, it’s been awhile…) That said… yeah, it couldn’t hurt to put a free CloudFlare CDN in front with automatic image optimization, for example.

Thats not enough. It was completely bloody unnecessary to waste enormous amounts of co2.
And critical thinking should lead to the realization that not many people have to solve the - albeit small - mistake of an individual via Cloudflare or similar, but rather someone should do it correctly right away. And if he has no knowledge of frontend, he should not do things he has no knowledge of.
