As an end user, I don't care about your web fonts, and I suspect others think the same. Usually designers push for them with concerns of brand image and consistency between platforms. I couldn't care less that I get a different font on Linux than what you design for on your Mac.
On the other hand, I care about the loading time of web sites and the privacy issues brought by the pervasive use of Google Fonts.
