I'm sure GitHub Actions are more intensive, but that doesn't make it harder to scale, which is what martinald said.

That infra scaling is what the cloud provider can easily offer.

Meanwhile, GitHub repos/issues/PRs is all the business logic that they've written, evolved over time.

Many coupled distributed DBs, indexes, consistency concerns, etc.

That's trickier to scale.
