Does React Flow still advertise itself unless you pay the developers at least $169/month?

You can programmatically remove the watermark, either via a flag or by changing the source code. > [1] No, you can do whatever you want with it since it’s MIT But if you use it in a commercial project, they'll likely shame you if you don't pay - like what happened to OpenAI with Agent Builder: > [2] Hey @OpenAI :) We just saw that you are using our open source library React Flow We offer startup discount codes :) Let…

The entire concept of mitigating un-intended re-rendering by wrapping your bad abstractions in more abstractions is not a category of problem for Svelte devs nor is it inherent to the platform like some inevitably of scale. React is bad because its foundation is a bad abstraction (v-dom) and it’s spent over decade pilling on more leaky abstractions every year, leading to where we are now — clamoring over a mountain o…
