Aggressive Feature Gating and Monetization Pressure

medium addon

Kong, like other API tooling companies, faces strong pressure to monetize aggressively through paywalls and feature gating. As noted in community discussions, when a company's entire business identity is tied to being 'the API tool,' pricing complexity and feature restrictions become almost inevitable.

why they end up becoming unfriendly to developers or development teams when they all start with great intentions is because their entire business identity is tied to being 'the API tool.' Be it postman, insomnia (perplexes me even more why kong has to push it so hard), even bruno to some extent is forced to find a viable monetization strategy. In any case, all this creates strong pressure to monetize aggressively. When survival depends on one product, paywalls, feature gating, and pricing complexity become almost inevitable, even with good intentions.
