I think Wetransfer is just outdated. Yea it's been around for donkeys years but for a free uploads it's very limited to 7 days and 2 gb for a which for a dvd or larger upload means dividing it into seperate links and that can be a pain if you missed one and you whine for weeks for continuous reuploads.
And I think it's model was developed when there was smaller files compared to the massive size of flies we have nowadays.
Compared to my current favourite 10 gbs and 30 days and not a single cent. Oh and you don't need to split it into individual links and 30 days should be a reasonable time frame for everyone to have a chance to download compared to the Wetransfer scenario.
