One can not simply trust Google. While I personally like the MIT licence more, I think it is time that the GPL or variants of it (Affero etc...) get used a lot more. It worked very well with the Linux kernel. Corporations keep on abusing this.
There are permissively licensed alternatives to most copyleft projects and they're increasingly the better options. You aren't going to reverse that by licensing niche projects as copyleft. Companies wanting to avoid copyleft can make permissively licensed replacements more easily than ever.
