I'd conjecture even further. The most valuable users of LinkedIn, those with in-demand skills, are more likely to be running a high-spec'd device where they don't care about these issues.

On my phone, 500MB would put you as ~30 largest app on my phone. Those largest 30 include, messages (large attachments), photos app, music/media (downloaded for offline play) and a variety of junk games I never play.

I'd have to delete LinkedIn 40x to save the same amount of space as the dozen or so junk games I have on my phone.
