I am not sure what you are looking at, but when I go to the 1password page from my mobile I see big buttons with: memberships, families, business and team, Mac, Windows, Linux, IOS, apple watch, android, 1password in the browser, scim Bridge, cli, secrets automation, ssh, desktop betas, browsers,android betas, IOS betas, previous versions.
Now that is a whole different level of confusing then keepass. I mean I generally know what I'm looking for, but wouldn't know if I should click on the families or Linux button for example. So I think this refutes your point that market share is due to the download page.
