Suspect that's more a map of antiproselytising laws, given it is coming from what appears to be a an evangelism focused organisation and the inclusion of countries like India.
To my knowledge Open Doors is purely looking to provide aid and support for Christians, rather then being evangelism focused.
"Open Doors is a
non-denominational mission supporting
persecuted Christians in the world."
Antiproselytising laws are probably a factor but the threats Christians face are undoubtedly much more then just that.
"Christians face harassment in 145 countries, Muslims face harassment in 139 countries, and Jews face harassment in 88 countries."

Persecution of religious Minorities in India has been noted to be increasing for a while with the rise of the BJP.
"Anti-Christian violence in India is
religiously motivated violence against
Christians in India.
[1] Human Rights Watch has classified violence against Christians in India as a tactic used by the
right-wing Sangh Parivar organizations to encourage and exploit
communal violence in furtherance of their political ends.
[1] The acts of violence include
arson of churches,
conversion of Christians by force, physical violence, sexual assaults, murders, rapes, and the destruction of Christian schools, colleges, and cemeteries.
[2][1]
Anti-Christian violence increased dramatically since the
Bharatiya Janata Party (BJP) started its rule at the center in March 1998. The
Vishva Hindu Parishad (VHP),
Bajrang Dal, and
Rashtriya Swayamsevak Sangh (RSS) are the organizations which have been most frequently accused of inciting the violence.
[1]
Hundreds of incidents of violence against Christians are reported by various organizations every year. India's ministry of internal security and its
National Commission for Minorities (NCM) officially list more than a hundred religiously motivated attacks against Christians each year.

As of 2020, the
USCIRF placed India as Tier-1 in minority persecution along with countries like
China, North Korea,
Pakistan and Saudi Arabia.
