These sorts of groups always consolidate in the end. Its no different to businesses merging like Facebook buying a startup.
Cybercrime, particularly ransomware, is business not a hobby. Its awful shitty business, but its business none the less.
As long as blackhat money is higher than whitehat money there will always be a cybercrime business.
Especially since the barrier to entry for blackhat cybersecurity is much, much lower than whitehat.
Hackers don't have to have a certification that costs thousands of pounds that requires 5 years of experience and two other qualified people to vouch for you. You probably just need Tor and a proof fo concept attack.
Hackers also dont care about ISO 27001, ISO 9001, UKAS audits, cybersecurity insurance (and all the bullshit that goes with it) and so on.
Hackers get paid far more for doing far less. Whitehats get paid next to fuck all for doing 80% paperwork.
