Unfortunately, it is very sad to see many privacy companies using this terrible service, for example Proton Proton support and Zendesk | Proton
Zendesk also created a fake band called “Zendesk Alternative” just in an attempt to pollute the Google results if you search for an alternative to Zendesk. According to this HN comment.
Are there any good open source alternatives to Zendesk which offers the same services that the companies uses the most?
There is a good alternative named Zammad. It has a bit of a WordPress/Odoo like structure set up with a commercial hosted version and an open source offering.
Not sure what is unethical about when a company doesn’t respond adequately informing the people using their products that they are at risk. Otterly bad take on the situation looking at the presented information
