The vastly lower attack surface in PDF viewers built into browsers has been quite frustrating for me. I've seen Adobe vulnerabilities in the wild, and I've seen the improvements to an organisations security by removing Adobe Reader. Not to mention, the immediate reduction in labour of managing its colossal updates regularly. However, try to remove Adobe PDF in a business with more than a few people, and ime, it's only a matter of time before you start getting demands for Adobe Reader. End users receive complex PDFs the reader in Chrome and Edge can't deal with more than tech people realise. I hit this myself recently, having decided to spend a week learning TLA+, and finding the published Hyperbook is just totally broken without a third party PDF viewer.
