I think this is aiming at 2GB Memory Tier. For majority of VPS that means they could move from $20/month to $10/month.

The problem is most popular Cloud/VPS ( DO, Linode, Vultr, UpCloud ) this tier gets you 1 vCPU only. Not sure how well this will work. Will have to test this.

Or as others have mentioned, just use Gitlab.com
