Over the years, Krishnaiah has also been actively involved with organizations like the Rashtriya Swayamsevak Sangh (RSS), Akhil Bharatiya Vidyarthi Parishad (ABVP), and the Andhra Pradesh Social Welfare Hostel Students Union.

Additionally, Krishnaiah's efforts resulted in the construction of over 600 residential colleges across Andhra Pradesh and Telangana, offering educational opportunities to students from weaker sections.

Despite an attempt by private engineering management to offer him ₹15 lakhs as a bribe, he refused and continued to push for reform, resulting in the successful implementation of reservations.

Krishnaiah has also been involved in various legal battles and protests, including a fight against the construction of the Almatti Dam and the campaign to ban single-number lotteries in Andhra Pradesh.

Over his four-decade-long career, his activism has led to the issuance of over 2,000 Government Orders (GOs), addressing welfare, education, public health, and social justice issues.
