This is a pet peeve of mine.
There is a reason the browser is refered to as the user agent. Because it is meant to exercise agency regarding the display of HTML elements and other web content on behalf of the user. This is the reason <strong> is preferred over <b>, <em> over <i> - the former are indications of the writer’s intent - express this part strongly, emphasize this part, in a medium-appropriate way consistent with the user’s preference - the latter are indications of a typesetter’s intent, ignoring the fact that not all of the readers will be using a typeset medium.
You have your preference as to how links should be indicated on your screen. How nice for you. Colourblind people, and users of cellphones and text-only browsers and screen readers and braille readers have their own. Please stop trying to break people’s custom stylesheets and user agent configurations.
