I wish , every company has their own app to use , they will invite you to their conference by default, asking 10 people on the call to change for 1-2 is not feasible.

Many of them cannot install any new native application on their desktop / phone without IT approvals or their vpn does not allow traffic to consumer apps like Hangouts . They also need to record for compliance , pre-Covid some apps like Webex are connected to their conference room bridges using dedicated lines and hardware etc

Family / friends do not use use biz tools , it not easier to convince Apple users who like FaceTime, messenger is popular in few countries , wechat in China , WhatsApp in other places .

It is easier install another app rather than trying to get your grandma to switch from one thing someone installed on her phone and she learnt to use.
