Agreed, I think the monopoly scenarios play out similarly/worse to the lock in ones -- monopolies are basically the extreme case of lock in. They're the ultimate removal of end-user influence on purchase decisions. Frustratingly, well-designed competition isn't necessarily enough, especially for b2b. Even when there is a challenger, that mostly impacts new customers. For locked in ones, renewal cycles and implementation burden may make it more 6-10 year levels to even be a serious conversation as long one as the legacy product functions. There are only so many Global 10K's, and that's a good chunk of the b2b user population. An interesting way to avoid the trap is 'mission focus'. If a company culture is mission-focused -- which is often easier in founder-led scenarios -- then decisions come from more than these $ reactions.
