If that individual is distributing his writings or speech by mass media, he is part of the press, or at a minimum exercising his right to freedom of the press. Wether it is through pamphlets, magazines, radio, video or online text, etc.

Here is what the Swedish National Archive writes on the subject, and I share the same view:

"When freedom of the press was introduced in 1766, many people wanted to express their opinions and spread their ideas. At this time, it was through shorter publications that people could communicate and reach many readers. A flood of printed material emerged, completely uncensored."

Some printers started to print the minutes of the courts to distribute them to the public. This way, people could read and see for themselves how the country was run and information could be disseminated in a completely different way than before. This became a profitable business idea. Freedom of the press and the principle of public access became a weapon for ordinary people against those in power and their decisions."
