I'm wondering if my lived experience is common and if there are any well-known statistics to back-up or reject the claim that zero-install is very important to encourage product usage.
(My career is not very product-focused, so this is all very foreign territory to me.)
This has inspired me to create a user account system with anonymous guest accounts. You can use the system right away, then upgrade to a full, permanent account if you wish to keep using the service. Kind of like a shopping cart where you get the option of creating an account at checkout.

On my PC, I am more likely to install applications that are portable/self-contained. If it's on https://scoop.sh/ I will install it without hesitation.
