That brand-name anchors signal a "strong brand" is unconfirmed; Google documents anchor text only as a description of the target page (Linking Text). Brand anchors are still what a natural link profile looks like, because people link to a company by its name or URL, and they avoid the keyword-optimized anchors Google names as spam. If your Search Console 1 Top linking text is mostly exact commercial phrases rather than your name, someone has probably been building links.
