It is not true. It is correct that Thomas Edison wasn't the first to think of or invent an electric lamp, but the one to make the light bulb more commercially viable and the first to successfully bring it to market. However, Nikola Tesla was not involved in the lightbulb.
Despite his contribution, what Edison actually did in history still contrasts strongly with his well-known inventor stories and makes many people consider him as an liar. Meanwhile, Tesla's less-known innovations in electricity distribution, radio, wireless power, etc. together with his "mad-scientist" rumors makes him the "forgotten selfless inventor". Though there is no evidence that they deeply hate each other, their ideolgies did clash fiercely in the War of the Currents between the Westinghouse and Edison companies. The idea of a feud between them involving stealing patents, lies, and sabotages also began to get popularity in literature, movies, games, .etc. Therefore, it is very common that people will consider contributions related to Edison to be stolen from Tesla.
