Ask HN: Why Download a Downloader to Download an app?
3 by phl | 2 comments on Hacker News.
Why do some companies distribute thair downloadable software through a downloadable custom downloader instead of offering the full installer directly to download? It has puzzled me several times throughout the last 20 years. I can not come up with a good reason. Especially when the custom downloader doesn't suppoert resuming interrupted downloads, display remaining time, current download speed or how much data is being downloaded. Notable example is the Spofify (Mac) downloader. I would really like to know what are good reasons from a UX, business or technical perspective to do that.
