G-Suite Gmail bug question

I am trying to figure out why Google believes this "by design" feature is good for the user. When using Gmail, specifically only when using Gmail as part of the G-Suite applications (the problem does not exist in the free version of Gmail) does this issue arise and I can't imagine that we are the only company frustrated by the problem.

When creating a signature for emails, if you want to insert an image in your signature (i.e. a company logo) you are only presented one option to insert the image from a URL (in the free version you can upload images and link from images in your Google drive). You cannot use URLs from images stored in your Google Drive, even if you have the permissions set to anyone on the web can see. If you attempt to use a Google drive image it will show as a broken image in the signature.

Google has confirmed that this is "by design" and that you are supposed to only use images hosted on your website or elsewhere on the web. While that's fine, I am more curious why they think this is the best option. If you use a regular old free Gmail account everything works fine. Thoughts?
