On Hetnzer (not affiliated), at this moment, i7-8700 (AVX2 supported) with 128 GB RAM, 2x1 TB SSD and 1 Gbit uplink costs 42.48 eur per month, VAT included, in their server auction section.
What are we missing here, besides that build farm was left to decay?
In the former case, I fail to see how ME or its absence is relevant to building Android apps, which they do using Google-provided binaries that have even more opportunity to inject naughty bits into the software. In the latter case, I better forget they exist.

To do a supply-chain attack on Google's SDK would be much more expensive and less likely to succeed. Google isn't going to be the attacker.
The recent attack on AMI/Gigabyte's ME shows how a zero-day can bootkit a UEFI server quite easily.
There are newer Coreboot boards than Opteron, though. Some embedded-oriented BIOS'es let you fuse out the ME. You are warned this is permanent and irreversible.
F-Droid likely has upgrade options even in the all-open scenario.
