Is WhatsApp safe for companies? They are not GDPR-compliant, so rather look at Self-Hosting

A study conducted by the technology company Guild showed that almost half of UK workers (41%) admitted to using the messaging app for work. And even though WhatsApp has penetrated the corporate space due to its popularity, companies are in search of a more reliable secure messaging platform.
Italy’s data protection agency contacted the European Data Protection Board (EDPB) in order to demand clear information over WhatsApp security. Besides that, some Indian and multinational companies have even issued advisories to employees asking them to use WhatsApp with caution and stop using the platform for critical business calls, as reported by Economic Times.
Yes it's well worth considering rather self-hosting something like RocketChat, Matrix, Elgg, or similar that does not attract the heavy subscription costs, and you have 100% own control over all data.
