Closed issue by waynevanson on void-packages repository

https://github.com/void-linux/void-packages/issues/27998

Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->

### System

* xuname:  
  Void 5.9.16_1 x86_64 GenuineIntel uptodate rrFFFFFFF
* package:  
 spotify-1.1.42_2

### Expected behavior

Installing package works without any errors.

### Actual behavior

`post_extract()` calls `message_error()` because the checksum of Spotify's EULA does not match the current.

```bash
post_extract() {
	curl -L https://www.spotify.com/us/legal/end-user-agreement/ |
		w3m -dump -I utf-8 -T text/html |
		sed -n '/Spotify Terms and Conditions of Use/,/^USA$/p' > EULA

	filesum="$(xbps-digest EULA)"
	if [ "$filesum" != "$_license_checksum" ]; then
		msg_error "SHA256 mismatch for EULA:\n$filesum\n"
	fi
}
```

### Steps to reproduce the behavior

- enable restricted packages
- `./xbps-src pkg spotify` in `void-packages/`

### Questions

@teh-jazzman What is the reason behind checking the EULA and throwing an error?
