Until they inevitable use Google, and it shows a big popup saying something like "Hey there you should use Chrome its way better and faster, click this button to get it" and then they end up with Chrome. Its basically how Chrome got such a large share of the market despite default browsers like Safari and IE/Edge.

Didn't Chrome also come bundled with other software like torrent clients? That is, unless you unchecked a checkbox in the installer for these software, you ended up with Chrome installed? Unless people were careful to pay attention to every checkbox on every installer, Chrome could end up installed without their knowledge.
