🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Use the unmodified canonical AGPLv3 text.

This file changes recipients to receivers in multiple clauses. The official GNU AGPLv3 text uses recipients in these locations. (gnu.org) Because the license states that verbatim copies must not be changed, restore the canonical wording before merging.

Proposed correction

- "Licensees" and "receivers" may be individuals or organizations.
+ "Licensees" and "recipients" may be individuals or organizations.

- give all receivers a copy of this License along with the Program.
+ give all recipients a copy of this License along with the Program.

- You need not require receivers to copy the Corresponding Source
+ You need not require recipients to copy the Corresponding Source

- transferred to the receiver in perpetuity or for a fixed term
+ transferred to the recipient in perpetuity or for a fixed term

- modified or installed by the receiver
+ modified or installed by the recipient

- the receiver automatically receives a license
+ the recipient automatically receives a license

- your receiver's use of the covered work
+ your recipient's use of the covered work

- automatically extended to all receivers
+ automatically extended to all recipients
