Is it permissible to download academic articles from the internet for use in a master's thesis, with proper citation, in cases where copyright issues and prices vary?

Intellectual property rights hold a protected financial value for their owners, and it is impermissible to infringe upon them. Downloading content from the internet is permissible if it is not protected by clauses prohibiting such actions, or if it is available for free. Quoting from online publications is permissible without downloading or copying them, provided there is honesty in transmission and the quotation is clearly attributed to its author. For this, the content owner's permission is not required, even if they explicitly state a prohibition.
