Foram retirados alguns links da Udemy para cursos pagos.
Precisa checar os cursos das demais linguagens, não pude fazer isso.
Provavelmente os demais cursos Udemy que ainda são gratuitos se tornarão pagos no futuro, e deverão ser removidos da lista quando isso acontecer.
Provavelmente este repositório está sendo usado para SEO e SEM. Portanto, sugiro que seja discutida a inserção de links para empresas que alteram a visibilidade de cursos que, no início são gratuitos e, posteriormente são alterados para pagos, fazendo com que esse repositório sirva para publicidade gratuita.
