To be fair, Indonesia is hardly alone as a republic to have elected an appalling character for a leader. If anything, they're somewhat late to this past decade's wave.
But that someone is wrong. Pointing out past strongmen (which both Suharto- and Sukarno, really, were) have led Indonesia in the distant past is not the same as Subianto being democratically elected into office and replacing the mainstream Widodo and ending the Era Reformasi. Subianto exists in the same company as Duterte, Modi, Erdogan, Bolsonaro, Meloni, Milei; 2010s and onwards figures.
Berlusconi is a perfect precursor to this type of character. But I'd say Conte and the Five Star Movement is far more populist and part of a global wave than Bunga-Bunga was.
They were early adopters of appalling character leaders, Suharto was elected in 1968 after seizing power and self appointing in 1967.
He was repeatedly elected for thirty years (with varying amounts of opposition and rigging during those decades).
