Applying strictness this way will lead to nothing apart from the realisation that it’s marketing. And that much had to be clear before reading the Kickstarter text.
They say “first […] for everyone”. In a strict sense it’s still a stretch, but arguably not as far a stretch as if vendors of prior phones with hardware switches would claim the same of their devices (e.g. Librem 5 as a Linux phone, PinePhone with DIP switches on the mainboard).
They say “You can install any of your favorite apps.”
Doesn’t mean 100% of them would work 100% of the time given the degoogled nature of /e/OS … but you can install them.
In “Murena Benefits X Others” there’s more than one place where the “Can be true or not depending on the phone” indicator should go additionally.
It’s marketing, an ad.
