@LoyceV If you think that everyone should download and verify the blockchain on their own and not rely on 3rd party downloads may I ask why you are compressing it?
Because I can 
I mean, why not? I believe in options and freedom to choose.Quote
Are you planning on releasing this
I just did

and why?
Because BADecker asked for it.Quote
I do not think you have bad intentions I just fear that newbies or people that do not know the risks might download this thinking it is a good thing to do and is normal.
If someone downloads 397 GB without knowing what he's doing, he can't be helped.Quote
I think you should probably include a warning saying that this is not normal and you should download & verify the blockchain yourself.
There is a warning:If I want to start my own full node, is it better to simply let the client update on its own?
Yes.I guess for someone who wants to look around the software with a full blockchain but not use it for integrity could find a use for downloading the entire blockchain from a quicker source then direct but that is all I can think of.
It may not even be faster. Bitcoin Core downloads from multiple sources, and some of them are probably much closer than my server.
