Not that I think there's a conspiracy, I don't think one has to try very hard to imagine reasons why the powers that be would suppress such discoveries.
Consider for instance how many US citizens are still religious today, and largely govern their lives according to religious beliefs. Consider how the current president has deliberately weakened the separation of church and state by making it legal for churches to be political - pastors of tax-exempt churches can now outright advise congregation on who to vote for.
Discovery of life elsewhere threatens the foundation of a lot of religious dogma.
