This is the trust placed by end users in Microsoft and their development. When Edge was first launched, in a rather basic form, with limited extension support, we used to receive complaints from people who'd bought a security suite and wanted a refund as their new security wouldn't support Edge (overlooking this was an issue with Edge, not their security). Despite having far more powerful alternatives, users paranoid about the dangers lurking around the internet would insist on using Internet Explorer. Microsoft never appears to be completely happy with their web browser.
