*Disclosure: I run a preprint server that "competes" with TechRxiv at https://engrxiv.org https://engrxiv.org. I'm a little salty about TechRxiv/IEEE as IEEE has a copyright transfer policy that permits posting preprints at approved servers. I applied to have engrXiv recognized as an approved server but received no response. Shortly after that TechRxiv was launched. Currently the only approved servers are still ArXiv and TechRxiv.
