Your example is actually the only time I've ever seen this side-by-side-style login page with the form on the right. Mailchimp, Quickbooks, and Alliant CU, for example, use the same layout as OP. I'd guess that Rippling is really trying to push their marketing, which is why it's on the left. Source: almost 3 years ago

And, of course, you need a Mailchimp account. If you still haven’t had an account, create a new one here. - Source: dev.to / over 3 years ago

I want to use old software from 2011 (https://sourceforge.net/projects/nokuntu/). It doesn't exist in the official Ubuntu repository anymore. The .deb package from sourceforge has a big list of unmet dependencies. This is the use case where Linux fails miserably compare to Windows. Every time linux distro updates, all packages have to be updated. On windows, you build it once, and it works even 10 years later.... Source: about 2 years ago
