I'm curious why you think that. From my perspective, you should do what is best for yourself and your users. I think you should definitely be leveraging things like CDNs that are low effort and high impact to save yourself time and help your users. Not using things that are closed source and from megacorps feels like a luxury that a lot of people cannot afford. Not monetarily, but in terms of time and effort. When I'm working on a side project I want to remove all the friction I possibly can so I stay motivated and keep working on the project.
