I was hoping to get some debate going, on the best and purposes ethical thing to do if you got paid for developing a website around wordpress.
Let me lay out the scenario a bit more clearly. You get hired to produce a website for a client, after having some discussions it becomes clear that they don't want a static website which will only get updated every 6 months, they want something a bit more fluid, more easily up-datable, not necessarily a blog but a front page and a few pages which once you've done your work they could easily alter the content of for themselves from inside wordpress.
So you do your work, it's mostly your own, but you rely on a few plugins to get all the functionality they need and follow some of the advice for coding a theme for wordpress from various different sources.
My question comes about when thinking about the money side of things. Usually you might just charge the client and hourly rate for your time plus expenses, but should you actually add on a little and donate it to wordpress and the authors of the plugins you've used? If you think you should add some on for the use of wordpress and the plugins, how do you work out how much?
