I don’t agree that that’s a problem with small tech. Startups get bought and are shuttered; big companies change priorities and drop products. I don’t see a big difference.
Sure, but getting ignored or people moving on is hardly exclusive to Small Tech. In my experience, it's far more prevalent in growth-heavy startups than in small businesses.
There are a lot of big tech products where the megacorp has lost interest. Google has websites dedicated to listing their abandoned products or services.
