I think there are 2 seperate issues here which are getting conflated. The first is a general issue around barriers to entry. If you charge for something you automatically exclude anyone who can’t afford it. Given the various complex statistical relationships between gender, ethnicities and income, this is going to affect the demographic of your users. I’m not making a value statement about this.
The second slightly seperate point is that a shiny new tool still in development, actively seeking people to contribute to it and guide its direction should get input from as wide a range of users as is practical. The privileged westerner is unlikely to be able to predict the usability issues that non privileged westerners will have further down the line as well as the non privileged westerners could have done, had they had the opportunity to contribute.
