Here it’s important to differentiate and it’s not so easy to label Zulip as fully trade-free. 1. https://zulip.com/ is NOT trade-free. There are plans that one can subscribe to in the “cloud”: https://zulip.com/plans/#cloud and even in self-hosted version: https://zulip.com/plans/#self-hosted 2. However, there is a “free-community-plan” for certain groups of people (in education or non-profit for example): https://zulip.com/help/self-hosted-billing#free-community-plan

Ito ang dahilan kung bakit maaaring lagyan ng isa si Zulip bilang trade-free para sa "Mga open-source na proyekto, Pananaliksik sa isang akademikong setting, tulad ng mga pangkat ng pananaliksik, cross-institutional na pakikipagtulungan, atbp., Mga organisasyong pinamamahalaan ng mga indibidwal na tagapagturo, tulad ng isang propesor na nagtuturo ng isa o higit pang mga klase, Non-profit na walang bayad na kawani o Komunidad at mga personal na organisasyon". Siguro ang 3 block ay maaaring angkop para doon?
