The premise of the article seems a bit flawed: Nigerians are not replicating hyperscalers, but more like building local Hetzners. And that is a fine idea!

A big problem for people doing this, however, is that peering is pretty much nonexistent in Nigeria (and, for that matter, most of Africa). So, traffic from, say, Airtel (where a lot of consumers are) to Globacom (which hosts a lot of major businesses), will not stay on the continent, but go via London or Marseille instead. And, also worth keeping in mind, from Lagos to those destinations, Joburg or Cape Town are actually double the distance, even though they might 'sound' closer.

So, yeah, I wish everyone involved all the best, but it will be an uphill battle. Convenience and latency make 'big tech' pretty hard to avoid, and 'strong crypto' would be my bet over 'local facilities', but, yeah...
