For me if people send me a WhatsApp or telegram link I don't join then became I don't know whom they are

What about social media such as LinkedIn and over a similar social network platforms

I have seen writers trying to get people to join their Substack, Websites and send they donations or buy books

Who does that stand with Medium

Also companies and individuals will always try to sell goods and services especially with platforms like medium

Where people are paying money to read online articles if they got the disposable income

To do that then they may pay for other services
