In my experience, despite Algo's effort, I still think it's much harder than using a commercial VPN provider. This is not Algo's fault actually. Setting up an EC2 account is too complicated than it should, and the complex Amazon cloud ecosystem is not helping.
Anyhow, for best results with Algo, I recommend using multiple cloud providers in multiple locations, in case one of them is blocked.

- **unzip**: GNU doesn't support stdin as input. Use funzip to decompress stdin, but only extract the first file like zcat. BB support stdin and extract all files, through `unzip -`.
- **sed**: BB doesn't support -z argument which is used to find/replace \n new line character. A [workaround](https://stackoverflow.com/a/1252191) is `sed ':a;N;$!ba;s/\n/<new character>/g' file` or `sed -e ':a' -e 'N' -e '$!ba' -e 's/\n/<new character>/g' file`. GNU `sed -z 's/\n/<new character>/g' ` works.
- **bsdtar**: Since GNU's zcat and funzip can only extract the first file, in addition to BB's unzip, another alternative is bsdtar. bsdtar can be installed through `libarchive-tools` package. To extract zip from stdin, use `$ bsdtar -xf -`.
- **patch**: BB doesn't support `--backup` option. BSD doesn't support `--verbose` option.

The issue was only pinpointed after I ran snyk with `--debug`, which I should've used it in the first place anyway. The issue is due to BusyBox's patch doesn't support `--backup` option. Sigh, {% post_link gnu-vs-busybox-tools 'BusyBox versus GNU' %}, back at it again.
To install GNU's patch, simply add `apk add patch` before `npm install` in your CI config (e.g. `.gitlab-ci.yml`). The installation will automatically replace the BusyBox's patch symlink, so you don't need to.
