It has this fun homemade feel to it that is very reminiscent of the reshot movies in Michel Gondry’s 2008 film Be Kind Rewind, which makes sense considering that is where the term ‘Sweded’ originated.

It may be low budget relative to an MCU film, but it still likely took a fair bit of time and effort to make it as close as possible to the actual Captain Marvel trailer.
