The issue is that wisp owners are cowboys, who dont ever follow through with good practices. Their networks, often due to guides like this website, end up riddled with technical debt (Technical debt is usually but not always branded Mikrotik).
Starlink doesnt offer layer 2 services. Starlink doesnt offer half rate backup services. Starlink doesnt offer installation. Starlink can often be very congested.
A wisp operator can:
1. Pull fibre into an area and then distribute it via 60GHz.
2. Pull fibre a bit further away and use decent APs with good MIMO.
3. Use profits from the above to pull fibre closer and ultimately overbuild themselves in areas with enough density
4. Service extrmely deep rural customers who dont have other options.
5. Service MDU's with a reverse model of 60GHz to the building, then fibre to the appt.
What actually happens in practice is that anything more complex than bouncing 5ghz off of a tower is too hard, hiring someone intelligent to do it for them is too expensive and too hard and so small wisps just sell to bigger wisps who sell to fibre carriers or go bust.
