No, it’s not that easy. Matt Mullenweg personally owns the plugin repository and has weaponized it by literally stealing paid plugins from their developers as revenge. You’d have to create an alternative repository for your fork to actually have a healthy ecosystem, but the individual developers are financially disincentivized to follow due to Mullenweg. This makes for a very uncertain future for both the project and the ecosystem - and why risk it, when there are better options?
